I clicked a link to "bushisms" (I bet that word will be introduced to the Oxford English Dictionary in no time). All I can say is this : what he says may make no sense, but he definitely has a unique way of wording things. usually with words we've never heard before.
My personal favourites are
"They misunderestimated me"
"My job is a decision-making job, and as a result, I make a lot of decisions."
"Amnesty means that you've got to pay a price for having been here illegally, and this bill does that."
"The best thing about my family is my wife. She is a great first lady. I know that sounds not very objective, but that's how I feel. And she's also patient. Putting up with me requires a lot of patience." (yes, we know)
Now that last quote could have come from MY husband.
